Thanks for your response. You are asking my business contact info, description of my company, ...

As I wrote in my previous message, my goal is to develop a plugin for JOSM (http://josm.openstreetmap.de), to be able to download the GPS tracks from the GP-200 directly into JOSM.I am not a corporate user, I am an end user. OpenStreetMap is not a commercial project, it is an open source and open data project. It has more than 500,000 members around the world that record GPS tracks and update the map every day. Look at http://wiki.openstreetmap.org/wiki/Main_Page .

The communication protocol of the DG-200 has some differences compared to the DG-100's Communication Protocol. One key difference is the baud rate. The DG-200 is using a much higher baud rate, which is 230400. On the other hand, the baud rate of the DG-100 is 115200.
